DUO mXTENDTM: TWO INDEPENDENT RADIOS IN THE SMALLEST ANTENNA FOOTPRINT

USER MANUAL DUO mXTENDTM (NN03-320)

2 Last Update: April 2021


DUO mXTENDTM

Two independent radios in the smallest antenna footprint



What is DUO mXTEND?

DUO mXTEND is a dual-port, chip antenna component designed to embed up to two

independent radios in the smallest antenna footprint. The chip is designed to combine, for

example, Bluetooth and GNSS or Wi-Fi and GNSS into a single package. Due to its Virtual

Antenna technology, DUO mXTEND can feature many other wireless services, such as UWB

making it the ideal antenna part for indoor/outdoor tracking devices.

DUO mXTEND has been engineered so that usually no ground clearance around the

component is required. Only a minimum clearance underneath the exact footprint of the

component is needed to obtain the best radiation efficiency in most cases. Moreover, the

component has been designed for dual-mounting: either at the center edge of your device or

at a corner, making this antenna flexible and easy to adapt in a variety of devices and radio

configurations.

What is DUO mXTEND for?

DUO mXTEND current operating range extends form 1500 MHz up to 10.600 MHz, making it a

versatile component to cover any radio application within that range, including Bluetooth, Wi-

Fi, and UWB, but also 5G and CBRS. Its miniature and slim form factor, together with its no-

ground clearance and dual-mounting features makes it the ideal wireless connectivity chip

for small indoor/outdoor tracking devices and all kinds of miniature IoT sensors. Due to the

minimum footprint and size of the DUO mXTEND, embedded massive MIMO (e.g. 8 x 8) devices

are a good application, where the density of installed antennas in a PCB is inherently high.

What differentiates DUO mXTEND from other chip antennas?

Like every other Virtual AntennaTM product, DUO mXTEND is frequency neutral, meaning that its frequency response is not determined by the antenna component but designed by the electronics engineer through a simple matching circuit. Virtual AntennaTM technology enables packaging the desired multiband performance in the smallest ever form factor, which enables the whole mXTEND range of components featuring a tiny off-the-shelf, surface-mount (SMD) electronic chip package. That makes mXTEND components easy to be integrated in about any IoT device through a shorter and easier design cycle and a much more robust, reliable and costs effective manufacturing process.

In addition, DUO mXTEND is one of the Virtual AntennaTM products featuring VariantTM technology, which enables embedding multiple antenna boosting elements into a single chip. By embedding both an independent electric and magnetic booster, the chip features two independent ports/feeds that enable sharing the same antenna component by two different radios. This, together with the no-ground clearance and dual-mounting features, the DUO mXTEND provides all the flexibility needed to develop nearly any wireless device fast. Use the DUO mXTEND for any wireless IoT or mobile product and save critical space on your PCB, as it covers multiple radio needs for many IoT applications, including, GNSS, or Bluetooth, Wi-Fi, UWB and the high bands of 5G and CBRS, to name a few.

1. Through a combination of inductors & capacitors

obtain 50 Ohms of antenna impedance to optimize

the transfer of energy to your antenna

2. It is critical to fine-tune your MN throughout the

entirety the design process of achieve your desired

frequency response

Look here for an example of a matching network we found in

an DUO mXTEND application via simulation

STEP 3: Test your device

1. Perform a field test in which your antenna is placed

in its final housing. Fine-tune the MN if needed.

2. Use a network analyzer to adjust mismatch

3. Test the antennas efficiency with an anechoic

chamber

Look here for testing we did on our Evaluation Board, with

the DUO mXTEND integrated in our Anechoic Chamber

MATCHING NETWORK

DUO mXTENDTM needs two matching networks to connect to your device, a first for the

Bluetooth port, a second for the GNSS one (Figure 2). This section describes in (Figure 3) a

suitable matching network for DUO mXTENDTM and the resulting product specs when measured

in the reference evaluation board (EB_NN03-320-m-GNSS-BT) described in the previous

section. Please note that different tracking devices with different form factors, RF ground planes

and nearby components may need a different matching network. If you need assistance to

design your matching network, please contact [email protected], or try our free-of-charge NN

Wireless Fast-Track design service, you will get your chip antenna design including a custom

matching network for your device in 24h1. Other related to NN’s range of R&D services is

To ensure optimal results, the use of high-quality factor (Q) and tight tolerance components is

highly recommended (e.g. Murata components with part numbers as in Figure 3). The antenna

performance is always conditioned by its operating environment so that different devices with

different printed circuit board sizes, components nearby the antenna, LCD’s, batteries, covers,

connectors, etc. affect the antenna performance. Accordingly, it is highly recommended placing

pads compatible with 0402 and 0603 SMD components for a matching network as close as

possible to the feeding point of the antenna element. Do it in the ground plane area, not in the

clearance area. By tuning the matching network in your final design with your final surrounding

components (batteries, displays, covers, etc.) you will be able to optimize the antenna

performance without changing the antenna part.

MATCHING NETWORK The antenna performance is always conditioned by its operating environment. Different devices

with different printed circuit board sizes, components nearby the antenna, LCD’s, batteries,

covers, connectors, etc. affect the antenna performance. Accordingly, it is highly recommended

placing pads compatible with 0402 and 0603 SMD components for a matching network as close

as possible to the feeding point of the antenna element. Do it in the ground plane area, not in

the clearance area. This provides a degree of freedom to tune the DUO mXTENDTM antenna

booster once the design is finished and taking into account all elements of the system (batteries,

displays, covers, etc.).

This section will present the proposed matching network and specs measured in the

corresponding evaluation board (

MATCHING NETWORK

DUO mXTENDTM antenna booster needs a matching network to connect to your UWB RF

module. This section presents the proposed matching network and specifications obtained in

the corresponding Evaluation Board (Figure 11), which is an ideal case. Thanks to its versatility

the DUO mXTENDTM antenna booster can be easily tuned to cover different regions of the UWB

spectrum through just the proper adjustment of the matching network. The excellent tuning

capabilities of the DUO mXTENDTM makes it ideal to avoid unnecessary product redesigns each

time your product specifications and operating frequencies vary. It allows you to easily adapt

your design to different applications, market segments, and devices through just the proper

design of the matching network by maintaining the same antenna part.

Two different options with two different matching networks are presented herein to illustrate this

flexibility. The first one is used to properly tune the antenna performance to UWB channels ranging from 3.1-4.8GHz (Option 1). The second one can be used to cover channels operating

from 6.0-10.6GHz (Option 2).

The antenna performance is always conditioned by its operating environment. Different devices

with different printed circuit board sizes, components nearby the antenna, LCD’s, batteries,

covers, connectors, etc. may need a different matching network. Accordingly, it is highly

recommended placing pads compatible with 0402 and 0603 SMD components for a matching

network as close as possible to the feeding point of the antenna element in the ground plane

area, not in the clearance area. This provides a degree of freedom to tune the DUO mXTENDTM

antenna booster once the design is finished and taking into account all elements of the system

(batteries, displays, covers, etc.). To ensure optimal results, the use of high-quality factor (Q)

and tight tolerance components is highly recommended (e.g. Murata components (Figure 12).

ASSEMBLY AND MANUFACTURING Figure 18 shows the back and front views of the DUO mXTENDTM antenna booster (NN03-320).

Figure 18 – Pads of the DUO mXTENDTM antenna booster NN03-320.

As a surface mount device (SMD), the DUO mXTENDTM antenna booster is compatible with

industry standard soldering processes. The basic assembly procedure for the DUO mXTENDTM

antenna booster is as follows:

1. Apply a solder paste on the pads of the PCB. Place the DUO mXTENDTM antenna booster

on the board.

2. Perform a reflow process according to the temperature profile detailed in Table 9, Figure 20.

3. After soldering the DUO mXTENDTM antenna booster to the circuit board, perform a cleaning

process to remove any residual flux. Ignion recommends conducting a visual inspection after

the cleaning process to verify that all reflux has been removed.

The drawing below shows the soldering details obtained after a correct assembly process:

Figure 19 – Soldering Details.

NOTE(*): Solder paste thickness after the assembly process will depend on the thickness

of the soldering stencil mask. A stencil thickness equal or larger than 127 microns (5 mils)

is required.



The DUO mXTENDTM antenna booster (NN03-320) can be assembled following the Pb-free

assembly process. According to the Standard IPC/JEDEC J-STD-020C, the temperature profile
